Habitable zone - Wikipedia
In astronomy and astrobiology, the habitable zone (HZ), or more precisely the circumstellar habitable zone (CHZ), is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.

Feb 16, 2023 · In our solar system, the Earth is clearly in the Goldilocks zone with much of its surface covered by liquid water. Venus is too hot, Mars too cold, and Earth is just right.
Goldilocks Zone - NASA Science
Oct 23, 2015 · The 'Goldilocks Zone,' or habitable zone, is the range of distance with the right temperatures for water to remain liquid. Discoveries in the Goldilocks Zone, like Earth-size planet Kepler-186f, are what scientists hope will lead us to water––and one day life.
What is the habitable zone or “Goldilocks zone”? - Science@NASA
The distance Earth orbits the Sun is just right for water to remain a liquid. This distance from the Sun is called the habitable zone, or the Goldilocks zone. Rocky exoplanets found in the habitable zones of their stars are more likely targets for detecting liquid water on their surfaces. Why is liquid water so important?
The Habitable Zone - NASA Science
The definition of “habitable zone” is the distance from a star at which liquid water could exist on orbiting planets’ surfaces. Habitable zones are also known as Goldilocks’ zones, where conditions might be just right – neither too hot nor too cold – for life.
